Answer:
2·2·2·2 = 16
Step-by-step explanation:
everytime a number is raised by another, that means you are going to multiply the base number times itself as many times as the exponents tells you. this is a little but tricky to explain, so let me give you some examples:
2² → in this case the base number is 2 and the exponent is 2 as well, so you will multiply 2 times itself, 2 times:
2² = 2 · 2 = 4
2³ → in this case the base number is 2 and the exponent is 3, so you will multiply 2 times itself, 3 times:
2³ = 2 · 2 · 2 = 8
In the question asked, 2 is being raised by 4, so you will multiply 2 times itself, 4 times:
2^4 = 2·2·2·2 = 16
the same format will be used regardless of the base number and the exponent

What is the predicted profit when the number of items made (x) is 2,500, and the number of stores stocking the product (x2) is 5, using the estimated regression equation y=550 + 30x1 + 9x2? a. 1,345 b. 23,200 c. 8,095 d. 75,595
Answers
Answer:
d. 75,595
Step-by-step explanation:
Given the estimated regression equation :
y=550 + 30x1 + 9x2
if number of items made (x) = 2500 ; number of stores stocking the product (x2) = 5
Predicted profit (y) will be :
Substitute the values x1 = 2500 and x2 = 5 into the estimated regression model:
y=550 + 30(2500) + 9(5)
y = 550 + 75000 + 45
y = 75595
Hence, the predicted profit will be 75,595

Write an equation of the parabola that passes through the point (62,-490) and has x-intercept-8 and 72. Then find the average rate of change from x =-8 to x=2.
Answers
Part 1
The equation is \(y=a(x+8)(x-72)\).
Using the point \((62, -490)\) to solve for \(a\),
\(-490=a(62+8)(62-72) \implies a=\frac{7}{10}\\\\\therefore \boxed{y=\frac{7}{10}(x+8)(x-72)}\)
Part 2
When \(x=-8\), \(y=0\).
When \(x=2\), \(y=-490\).
So, the average rate of change is \(\frac{-490-0}{2-(-8)}=\boxed{-49}\)

whenever we add 1 to the number of team wins, the attendance number goes up by 15. that is a constant rate.
a constant percentage would change the absolute number of people attending every time.
e.g. let's say there were 100 people attending last time. and the audience increases by 10%. so, next time there are 100 + 10% = 100 + 10 = 110 people attending.
they win again, and the constant percentage of 10% would add now 10% of 110 people = 11 people.
and so on.
the linear function "attendance" would be for x as the number of team wins :

∑f = 899+224+126+96+71+52+39+41+44+23+14+12+3+4+3 = 1651
Number of songs played over 100 times = 14 + 12 + 3 + 4 + 3 = 36
\(Percentage \ of \ songs \ played \ over \ 100 \ times = \mathbf{\dfrac{36}{1,651} \times 100} \approx \underline{2 \%}\)2. Mean of a frequency distribution is given as follows;
\(Mean = \mathbf{\dfrac{\sum f\times x}{\sum f}}\)

The initial population of a bacterial culture is 2000, growing at a fixed rate. Table shows the population every hour for six hours.
A. Find the equation that models this relation. (round to one decimal place).
B. Use the equation to find the population of bacteria after 12 hours after 24 hours.
Answers
Answer: A. To find the equation that models this relation, we can plot the data and look for a trend.
From the graph, we can see that the data follows an exponential growth pattern. The equation for exponential growth is:
y = ab^x
where y is the final population, a is the initial population, b is the growth rate, and x is the time in hours.
Using the data from the table, we can find the value of b:
b = y/x
where y is the population after x hours.
For example, after 2 hours, the population is 5000:
b = 5000/2 = 2500
We can repeat this process for each time period and find the average value of b:
b = (2500 + 3125 + 3906.25 + 4882.81 + 6103.51 + 7629.38) / 6 = 4275.5
Now that we have the value of b, we can find the equation that models the relation:
y = 2000(4275.5)^x
Rounding to one decimal place:
y = 2000(4.3)^x
B. Using the equation, we can find the population after 12 and 24 hours:
y = 2000(4.3)^12 ≈ 8,898,335.7
y = 2000(4.3)^24 ≈ 7.42 x 10^13

Answers
Answer:
Ann traveled 165 miles on 5 gallons of gas
Step-by-step explanation:
First we must know how many miles are in a gallon (in this situation). Last weekend Ann drove 132 miles with 4 gallons of gas, we can divide to find out how many miles she drove on 1 gallon. 132/4 = 33. This means Ann drove 33 miles on 1 gallon of gas. To get your answer, simply multiply 5 and 33. 5 times 33 = 165.

a. The probability that the first part is suitable is 40/48 = 0.83.
b. If the first part is suitable, the probability that the second part is also suitable is 39/47 = 0.8255. This is because if the first part is suitable, that means there are only 39 parts left in the shipment that are suitable.
c. If the first part is suitable, the probability that the second part is not suitable is 8/47 = 0.1745. This is because if the first part is suitable, that means there are only 8 parts left in the shipment that are not suitable.

What does UIF stand for? Show by calculation that the UIF paid by Gavin is calculated correctly Which month is this Payslip for? Calculate the missing values A to C How old is Gavin this year? Give the address of Gavin's work place. Gavin would like to contribute towards a Pension fund (7,5% of his Basic Salary). H would this affect his net salary?
Answers
If Gavin contributes towards a Pension fund (7,5% of his Basic Salary), then his net salary will be reduced by the amount he contributed towards pension fund i.e. R652.5.
1.1 Name of employee is Gavin Pillay. 1.2 UIF stands for Unemployment Insurance Fund. UIF is a benefit to provide short-term relief to workers who lose their jobs, or can't work due to illness, maternity or adoption leave. 1.3 The UIF paid by Gavin is calculated correctly.
Firstly, we need to calculate Gross Salary of Gavin, which is given as: Basic Salary + Overtime + M = R8700 + R1200 + R3201 = R13101Then, calculate total deductions from gross salary.
Total Deductions = PAYE + UIF = R1200 + 87 = R1287Hence, Gavin's net salary = Gross salary - Total Deductions = R13101 - R1287 = R11814Therefore, UIF paid by Gavin is calculated correctly as R87.1.4 This payslip is for the month of May i.e.
31/05/2023.1.5 Basic salary of Gavin = R8700. Deduct 7.5% of his basic salary to calculate his pension fund contribution. Pension Fund Contribution = 7.5/100 x R8700 = R652.5.1.6
Total deductions of Gavin includes PAYE, UIF and pension fund contribution.
Therefore, Total Deductions = PAYE + UIF + Pension Fund Contribution = R1200 + R87 + R652.5 = R1939.5.1.7
Gavin's age can not be determined as his date of birth is not provided.1.8 Address of Gavin's workplace is 21 Halsted Road, Pietermaritzburg?
